REPORT OF THE STATE BOTANIST I917 57 



The type (Hysterium c 1 a v i s p o r u m, Doth idea 

 clavispora C. &P.) was collected on the same host at Tyre, 

 September 1871. Doctor Peck also collected it at Watkins, N. Y. 



Rosellinia obtusissima (B. & C.) Sacc. 

 On decorticated branches of Acer. Sandlake. C. H. Peck. 

 Perithecia setose ; sporidia very obtuse, elliptic, nearly as broad 

 as long, 12 to 14 X 9 to 1 1 /A. The type ofSphaeria obtusis- 

 sima B. & C. is from Pennsylvania. 



Scleroderris fuliginosa (Pers.) Karst. 



On dead twigs of Salix sp. Bald mountain near Fourth lake, 

 northern Herkimer county. H. D. House, June 27, 1917. 



Saccardo's description speaks of the " late ambiente-effuso " 

 subiculum, which is again referred to in the note on character 

 given below the description. Phillips, however, does not mention 

 a subiculum. Otherwise the colors, size and septation of sporidia 

 agree with Karsten's and Saccardo's descriptions. 



Septoria coptidis B. «& C. 



The measurements given in Saccardo (Syll., 3: 526) call for 

 sporules 25 yu, long. On leaves of Coptis collected by C. H. Peck 

 at Grassy pond in the Adirondack mountains, the spots and form of 

 spores agree with the description, but the sporules are from 30 to 

 65 n long, averaging about 45 fx long. The pycnidia are epiphyllous 

 and from 72 to 125 yii in diameter. 



Septoria hedeomae Dearness & House, sp. nov. 



Spots brown, darker above, angular or suborbicular, mostly from 

 2 to 4 mm broad. Pycnidia epiphyllous, numerous, small, 35 to 

 65 /x in diameter; wall very thin, hardly visible if existent at the 

 summit; sporules continuous, straight or curved, 24 to 33 x i /x. 



On leaves of Hedeoma pulegioides. Highland Mills, 

 N. Y. C. H. Peck. 



The pycnidia on the leaves are much smaller and thinner walled 

 and the sporules shorter and narrower than the corresponding char- 

 acters of Septoria hedeomina Peck (Rhabdospora 

 h e d e o m i n a Sacc.) on dead stems and calyces of the same host. 

 Peck appears to have considered this a mere form of R , h e d e -
